Although it occurs naturally in manganese ores, manganous dioxide, which finds its principal application as a depolarizer in drycell batteries, is usually produced synthetically. Manganese ore is reduced and then leached with sulfuric acid. The solution is purified, and manganous dioxide is obtained by electrolysis.
